Hardness of Water

Water systems using groundwater as a source are concerned with water hardness since as water moves through soil and rock it dissolves small amounts of naturally occurring minerals and carries them into the groundwater is a great solvent for calcium and magnesium so if the minerals are present in the soil around a water supply well hard water may be delivered to homes

Archimedes principle

Suppose a rock s weight is measured as 10 newtons when suspended by a string in a vacuum with gravity acting on it Suppose that when the rock is lowered into the water it displaces water of weight 3 newtons The force it then exerts on the string from which it hangs would be 10 newtons minus the 3 newtons of buoyant force 10 − 3 = 7 newtons Buoyancy reduces the apparent weight of
